7. Ali ibn Ibrahim has narrated from from Yasir al-Khadim and al-Rayyan ibn al-Salt all have said the following.

“When the matter of the deposed Caliph (Amin) ended and it was established for al-Ma’mun he wrote to al-Rida asking to come to Khurasan. Abu al-Hassan in reply presented certain reason to justify his disagreement to the proposal but al-Ma’mun continued writing until The Imam found it out to be unavoidable and that will not leave him alone. He then left for Khurasan when abu Ja‘far was only seven years old. Al-Ma’mun wrote to him, “do not travel through the mountains and Qum. Take the road through Basra, al-Ahwaz and Persia. The Imam arrived at Marw. Al-Ma’mun offered him to command and lead the task of Khilafat (Leadership) but abu al-Hassan declined. He then offered the Imam to accept the post of the crown prince The Imam said that he may accept it under certain conditions. Al-Ma’mun said, “Say whatever conditions you like.” The Imam wrote, “I will assume this post with the conditions that I will nor issue any order or prohibitions nor issue any fatwa or judgment nor any appointment or dismissal of officers or change anything in the current system. You must excuse me in all such matters. Al-Ma’mun agreed to all such conditions. The narrator has said that Yasir narrated to me saying, “When it was ‘Id (the holiday) al-Ma’mun asked al-Rida to attend the program, lead the prayer and deliver the sermon. Al-Rida replied him saying, “You know the conditions between us. They did not consist of any such matters. Al-Ma’mun sent the message, “I only want there by to build confidence in the people and they would know your distinction.” He continued insisting until the Imam said, “O Amir al-Mu’minin, I would appreciate much if you would excuse me from such task and if you would still insist then I will out for this task in the manner that the Messenger of Allah and Amir al-Mu’minin Ali would do.” Al-Ma’mun then said, “You may do as you would chose. Al-Ma’mun ordered the servants guides to lead a procession to the door of abu al-Hassan saying ‘Allahu Akbar’ Allah is great. The narrator has said that Yasir al-Khadim narrated to me this. “People lined up waiting for the Imam on the roads and roof tops, men women and children. The guides and people from the army gathered at the door of abu al-Hassan . At sun rise the Imam took a shower, wore a white turban made of cotton. He let one end of the turban hang over his chest and the other end between his shoulder on his back. He tied his belt and asked his followers, “Do as I have done.” He picked up an arrow shaped staff and came out and we were along with him. He was bare foot and his gown was raised half way between his feet and knees and so were his other (long) clothes. When he walked and we walked along with him he raised his head towards the sky and Allahu Akbar (Allah is great) four times. It seemed to us as if the sky and the walls responded to him. the guides and the people at the door were ready and armed and decorated with the best dresses. When we appeared before them in such fashion and al-Rida appeared to them he stood at the door shortly and then said, “Allahu Akbar (Allah is great). Allahu Akbar (Allah is great). Allahu Akbar (Allah is great). Allahu Akbar (Allah is great) for guidance that He has granted us. Allahu Akbar (Allah is great) that has granted us the cattle. All praise belongs to Allah that He has granted us blessings. We all would raise our voices. Yasir al-Khadim has said that the whole Maw shock with the weeping, cries and shouts when they looked at abu al-Hassan . Many of the guides fell from their horses who would kick and throw their boots when they saw abu al-Hassan barefoot. He would walk about ten steps and pause and say Allahu Akbar three times. Yasir al-Khadim has said that to us it seemed as if the sky, earth and mountains would respond to him. The whole Marw had become one voice loud and tearful. Information of this was reported to al-Ma’mun and Sahl ibn al-Fadl, who had two official posts, said to him, “Amir al-Mu’minin, if al-Rida would reach the place of prayer in this manner people will into his devotees. Ask him to return home.” Al-Ma’mun sent his people to ask abu al-Hassan to return home. He asked to bring his shoes and wore them and rode back home.”
